How to use Schwarzkopf Fibreplex N°1 Booster - 500ml with bleach powder?
Prepare your bleach or colour mixture as usual.
Add Schwarzkopf Fibreplex N°1 Booster - 500ml to the mixture following Schwarzkopf’s mixing chart.
Have thick or coarse hair? Then use 50% less Booster than usual.
Mix everything well until you get an even consistency.
Apply the mixture to hair and leave on as normal.
Rinse hair thoroughly and follow with your regular hair care.
After bleaching, your hair is extra vulnerable. The Fibreplex N°2 Bond Sealer seals the treatment by closing the hair cuticles and locking in the Booster’s protection. Together they form a complete system supporting your hair before, during, and after treatment.
Why does this bond booster work so well against hair breakage?
Your hair breaks less and feels stronger after use because the Booster strengthens the internal structure of your hair during bleaching instead of fixing it afterwards. Maleic acid plays a key role: it protects your hair’s inside while the chemical reaction takes place. Amino acids also help by keeping hair flexible and hydrated so it feels less dry or brittle. The Booster protects your hair during bleaching and helps prevent breakage without affecting colour results. It’s a smart choice if you bleach often or have sensitive hair.
Is the Fibreplex Booster better than Olaplex for bleaching?
The question is Fibreplex better than olaplex for bleaching comes up a lot, and honestly: they work differently. Olaplex has a patented molecule designed to reconnect broken bonds in your hair. Fibreplex works more by protecting your hair during the process, keeping the hair fibre stable with film-forming agents and amino acids that support structure.
If you bleach regularly and want to prevent breakage, Schwarzkopf Fibreplex N°1 Booster - 500ml is a strong choice. If your hair is badly damaged from years of bleaching or chemical treatments, Olaplex No.1 might suit better due to its targeted repair. Want a full system from a strong salon brand that’s also easy to combine with aftercare at home? Then Fibreplex is the logical option.
How do I use Schwarzkopf Fibreplex N°1 Booster - 500ml at home without a hairdresser?
The Booster is a professional additive and only works combined with bleach or colour products, not as a standalone mask or treatment. You mix it into a specific ratio with your colour mixture.
If using at home, be sure to follow Schwarzkopf’s mixing chart. Too much can affect texture if you have thick or coarse hair. Unsure about the right amount? Start with the standard ratio and adjust based on your hair type.
Does the Fibreplex Booster replace trimming and aftercare post-bleaching?
No. Schwarzkopf Fibreplex N°1 Booster - 500ml greatly reduces breakage during treatment but it doesn’t make already damaged hair “new” again. Long-damaged hair still needs aftercare: regular trims, good moisture balance, and the right products.
The Booster works best as a preventive step before damage occurs. Combined with a good hair care routine, it gives your hair the best chance to stay strong and healthy—even after multiple colour treatments.
What makes Schwarzkopf Fibreplex N°1 Booster - 500ml right for your hair?
Schwarzkopf Fibreplex N°1 Booster - 500ml suits chemically treated hair like bleaching, heavy lightening, or colouring. Especially if your hair is previously treated, breaks easily or feels porous, you’ll notice a difference right away. After use, hair feels less dry and breaks less.
Want the full system? Combine the Booster with Hair Primer Porosity Equalizer Spray to prepare your hair. It evens out porosity so colour or bleach works more evenly. Interested in the full range? Check all products from Schwarzkopf.
